` AGENDA ITEM: Lift Station "B" Force Main Upgrade, Bid No. 0102-17 (Re-Bid)
Comparative Analysis with Force Main Relocation from Lift
,~ Station A
~,
SUBMITTED BY: Donna Kaluzniak, CEP, Utility Director
;.
~;
DATE: August 30, 2002
~"'° BACKGROUND: The project to upgrade the force main from Lift Station B (425 11th
~ ` St.) was on the City Commission agenda of August 26, 2002, with a recommendation to
award a reduced scope of the project to Gruhn May, Inc. The Commission directed staff
'"" to determine. if costs could be saved by re-routing the force main. from Lift Station A (460
Palm Ave.) from the five way intersection west on Plaza then north on Sandpiper to the
treatment plant.
...,
Completing the "reduced scope" project recommended previously would be required for
either upgrading -the force main from Lift Station B or rerouting the force main from Lift
~" Station A. The connection point on the east side of Sandpiper Lane would be the same
b -° for either option, and the relocation of the connections at the master lift station. will
reduce the pressure caused by having four lift stations manifolded into a 12-inch line.
The "reduced scope" portion of the project has been bid twice, and the cost has not gone
down. Therefore, staff's recommendation remains to complete the reduced scope project
at this time.
~°
` Regarding the cost comparison between the two force main options, installing the force
~, main on Plaza and Sandpiper would increase the length of force main by approximately
~ 1000 feet. In addition, there are potential conflicts with the proposed force main and
existing utilities on Plaza, which include a water main on the north side, water and sewer
,~„ mains on the south side, AT&AT Broadband on both sides and major BellSouth utilities
at various locations on the route. The force main would also have to cross the lagoon
near City Hall. Additional survey, design and permitting would be required for the
,~,, project. According to the modeling conducted by Smith & Gillespie, the additional
' capacity afforded by this.option would not be necessary.
~», Based on the information above, staffused a recent average bid price for force main
~ ' replacement of $80/LF to estimate the cost of relocating the force main from Lift Station
~:
A down Plaza and Sandpiper, and added estimated costs for survey, design and
., permitting. It appears that relocating the force main from Lift Station A would cost an
additional $60,000. This is a rough estimate, as a full survey and design have not been
completed, and linear foot costs are very much dependent upon the location and potential
r~* interferences of other utilities which were described above.

BUDGET: The budgeted funds available for this project are $130,000. As noted, the
reduced scope recommended for award is $127,598,25.

` Upgrade, Bid No. 0102-17 (Re-Bid) to Gruhn May, Inc. with a reduced scope in

~ AGENDA ITEM: Lift Station "B" Force Main Upgrade
Bid No. 0102-17 (Re-Bid)
SUBMITTED BY: 'Donna Kaluzniak, CEP, Utility Director
DATE: ~ } August 16, 2002

" = BACKGROUND: One of the recommendations of the Sewer Master Plan was to
replace the existing 10-inch diameter force main from Lift Station B (425 11'h St.) with a
new 12-inch force main. This force main carries wastewater from Lift Station A (460
~> _ _
Palm Ave.) and Lift Station B to Wastewater Treatment Plant No. 1 (1100 Sandpiper
„~, Lane), and the size and method of connection of this force main were determined to be
E restrictive, a contributing factor to sanitary sewer overflows during heavy rainfalls.
~~
~,,.,, The force main is located in an easement running through the Selva Lakes subdivision,
' and residents have built improvements over the easement, making access very difficult.
k y Aikenhead & Odom designed the replacement force main, specifying trenchless
s., technology be used within the easement to avoid disturbing the area. Staff prepared bid
documents.
~+ Bids were advertised, and seven invitations were sent to bidders, but only Gruhn May,
Inc. submitted the required documentation to prequalify for the original bid. Gruhn May
submitted bids using both the pipebursting and directional drilling methods, but both bids
~+ were significantly over the budgeted amount, and on June 24, 2002 the City Commission
rejected all bids and authorized staff to re-bid the project.
~^ The project was re-advertised, and two bidders prequalified and attended the mandatory
~ Pre-Bid Meeting on July 23, 2002. Two bids were received on July 31, 2002, both
utlllzlna the directiona] drilling method in tha r acam Pot .~ruo
~_.
~; _.
Gruhn May, Inc. is the low bidder, but both bids -were again well, over the budgeted
"~ amount of $130,000. Staff discussed options and consulted our engineers, and
determined that the City could still realize a significant improvement in system
performance with a reduced scope for this project, consisting of replacing only the
~ portion of the force main from the east side of Sandpiper Lane to the treatment plant, and
including the relocated force main connection points.

City staff contacted Gruhn May to ask if they would consider reducing the scope of work
"'"" while retaining the same unit prices, and they agreed. The cost for the project with the
reduced sco e of work will be $127,598.25:
Gruhn May, Inc. Slaughter Construction
Base Bid -Reduced Scope $110,955.00 $111,810.00
15% Contin enc $16,643.25 $16,771.50
Total Bid with Reduced Scope $127,598,25 $128,581.50
BUDGET.: Budget for this project was $130,000, based on the rough estimate
~,,, .provided iii the Sewer Master Plan. Aikenhead and Odom's determination of probable
costs after design completion was $ i 79,000. High prices from subcontractors, costs of
Y ~ bypassing lift station flow during construction, difficult access through the easement, and
,~,,, roadway crossings accounted for the high amount. of the bid.
